Research on Digging Control System of EBZ260A Cantilever Roadheader
In order to solve the deficiencies of poor quality and low efficiency of roadway section formation that exist in cantilever is roadheading machine using video monitoring and plane information control.Based on EBZ260A cantilever type roadheader,its control system is modified.Using visual measurement technology to accurately determine the position data of the roadheader,using air state sensors to accurately obtain the cutting operation environment data,as the basis of digital twin drive control,to build a virtual model of the roadheader and virtual scene coupling control logic,to achieve the precise tracking control of the cutting operation of the roadheader.According to the practical application,the new control system can improve the cutting control accuracy of the roadheader to±30 mm and the cutting control reaction speed to 0.1 s,which greatly improves the cutting efficiency and accuracy of underground cutting.
